The latest version 1.8.4 of the CryptoNight AMD GPU miner SRBMiner brings significant performance boost for all of AMD’s HBM memory based GPUs, namely the Radeon Vega56, Vega 64, Vega FE and the latest Radeon VII with HBM2 video memory. The performance boost for these video cards can be up to about 15%, so definitely worth upgrading any mining rigs with the newly released miner for the extra hashrate you will be getting… and that apparently goes for all of the supported algorithms! To take advantage of the extra performance boost you need to play around with the new parameter tweak_profile checking the level of tweak profile that your GPUs can handle and applying it. Apparently the improvement is based on memory timings modification thanks to the work of Eliovp and his useful AMD Memory Tweak Tool.
You can find the full changelog for the latest release quoted below. Do note that the developer fee is ~0.85% for both normal mode and algorithm switching mode as SRBMiner is a closed source miner available for AMD GPU miners only under Windows.
